Yesterday I responded to a fellow's question about the depth capabilities of the MX5 and low and behold, today I dig my deepest coin yet with it. I was hunting a spot where I found two large cents and a seated dime with my Explorer SE Pro. This place is soft clay and even the clad coins are very deep(7-8 inches). I had not had a very good morning with just 15 clad pennies and dimes, but again some were very deep. I was just about ready to jump to a new area when I got a whisp of a 87 to 89 signal. It would only hit occassionally, but when it would not hit, I got a break in the threshold. A really neat feature of the MX5 is the threshold. On extremely deep coins, I might get a quick high tone blip and when I check from another angle, I get nothing more than a break in the threshold, but a high number will flash on the screen. If this happens to you, by all means dig it. When I pinpointed today's deep target, it showed 8.5 to 9 inches deep. I dug a slightly bigger plug and when the target was not to be found with my pinpointer I was thinking rusty iron. When my 10 inch long pinpointer was all in the hole, I found the target a couple of inches off to the side of the very bottom of the plug. Since the plug was over-sized, I saw the edge of crusty coin on a 45 degree angle that I was thought was a clad quarter. I pryed it out with my fingers and it was a large cent. 1846 and decent shape! A ten inch deep coin on an angle. This detector is showing me more and more every time I use it. I am a big fan of Whites detectors and I have owned almost every one made in the last 15 years, but the MX5 is as high performing as the big boys and absolute breeze to adjust. Again, great job Whites.
